A year and a half ago security forces in the capital raised their alertness to a particularly high level amid warnings of a possible terror attack. Forces boosted their presence in the city and searched vehicles and suspicious individuals.

At the time, several roadblocks were set up in the Pisgat Ze'ev
neighborhood, at the French Hill
Junction and on the road leading from Ma'ale Adumim to the village of Hizma. In addition, security forces searched vehicles passing through the Mount Scopus tunnel.

At the time, the alert level was raised following a terror attack that was carried out in the south by a terror cell that infiltrated Israel
from Egypt.
